The best ice cream recipe ever I got from a physicist:
Cream + sugar + vanilla, stir until dissolved. Slowly add liquid nitrogen while stirring fervently until sufficiently frozen.
The stirring in of the liquid nitrogen not only freezes the cream, it prevents any cristallisation and fluffs up the ice cream by evaporating. Truly delicious!
Depends on the cream you use. But basically it doesn't really matter, you can also use milk, even skimmed milk. Any liquid icecream-mix works, only chunky stuff is problematic.
One time in grad school we used liquid argon that was going to boil off. Since argon is heavier than Alex the ice cream had a very interesting bubbly consistency.
Pretty much, it was weak at best, cozzyd seemed amused which was the intent, we all make mistakes and typo'ing Alex rather than air was worth a mild poke.
